Using the
Symfony components

Symfony framework is built on top of a set of decoupled and reusable PHP components called Symfony Components. They are becoming the standard foundation on which the best PHP applications are built on. You can use any of these components on your own applications independently from the framework.

Adding a Symfony Component to your application:

composer require

This requires to install Composer globally in your system.
